This product is a left-hand pistol grip designed for the Mamiya C Professional medium format film camera. It is black in color and comes in its original box from Japan. The grip is compatible only with Mamiya brand cameras and is a custom fit for the C Professional model. The product is a type of hand grip and is designed to make it easier to hold and stabilize the camera while shooting.  I am not an expert on camera equipment, so please ask any questions you may have.
